What is evaporation? Describe what happens at the molecular level during evaporation.
jasenka [17]
 Evaporation happens<span> when atoms or </span>molecules<span> escape from the liquid and turn into a vapor. Not all of the </span>molecules in a liquid have the same energy. <span>Sometimes a </span>liquid<span> can be sitting in one place (maybe a puddle) and its molecules will become a </span>gas<span>. That's the process called </span>evaporation<span>. It can happen when liquids are cold or when they are warm. It happens more often with warmer liquids. You probably remember that when matter has a higher temperature, the molecules have a higher </span>energy<span>. When the energy in specific molecules reaches a certain level, they can have a </span>phase change<span>. Evaporation is all about the energy in individual molecules, not about the average energy of a system. The average energy can be low and the evaporation still continues. </span>

Which salt is produced when sulfuric acid and calcium hydroxide react completely?
AnnyKZ [126]

Answer: Option (4) is the correct answer.

Explanation:

When sulfuric acid reacts with calcium hydroxide then it results in the formation of calcium sulfate and water.

The chemical reaction for the same will be as follows.

     H_{2}SO_{4} + Ca(OH)_{2} \rightarrow CaSO_{4} + 2H_{2}O

Thus, we can conclude that CaSO_{4} salt is produced when sulfuric acid and calcium hydroxide react completely.

How much heat in joules is required to heat a 43g sample of aluminum from an initial temperature of 72˚F to a final temperature
Stels [109]
The first step to answering this item is to convert the given temperatures in °F to °C through the equation,

   °C = (°F - 32)(5/9)

initial temperature: 72°F

    °C = (72 - 32)(5/9) = 22.22°C

final temperature: 145°F
   
    °C = (145 - 32)(5/9) = 62.78°C

Substituting to the equation,

    H = mcpdT
    
    H = (43 g)(0.903 J/g°C)(62.78 - 22.22)
   
   H = 1574.82 J

<em>Answer: 1574.82 J</em>
